An Adaptive and Efficient Peer-to-Peer Service-Oriented Architecture for MANET Environments with Agile Computing

Abstract

Realizing adaptive and efficient peer-to-peer Service-oriented Architectures for MANET environments is a challenging problem. In particular, robust and efficient service discovery and service migration are critical in the constantly changing and bandwidth limited MANET environments. In these scenarios, service migration lays the foundation for self-adaptive architectures. This paper describes the agile computing approach to peer-to-peer service discovery and service migration and provides a performance evaluation of these functions in the context of the Agile Computing middleware. The experimental results presented in the paper show that applications built on top of the Agile Computing middleware are capable of opportunistically exploiting transient computing resources in the MANET environment.

Deployment of Service Oriented architecture in MANET: A research roadmap

“…Whereas [12] focuses on policies of service composition and their effects on the SOA performance. In [13], an agile computing based approach is presented for migrating existing application to MANET environments. Also [14,15] present a comprehensive summary of discovery protocols that can be used for SOA on MANETs.…”

“…There several research efforts have been provided on these architectures. The approaches in [1,4,13,19,20,21] proposed methodologies to deploy SOA on distributed or P2P MANET. In [4] an approach has been proposed with the concept of tools for the deployment of SOA in dynamic environment like MANET.…”

“…Growing interest in deployment of SOA on MANET has recently emerged because of several reasons [13,22]. These includes, (i) Simplicity of design, (ii) support of dynamic composition of services at runtime , thus enabling the ad hoc realization of complex distributed applications to be deployed successfully on mobile nodes, (iii) applications can be built as modular services, which are better suited for deployment in mobile and resource-constrained nodes, (iv) allows dynamic replacement of service, which enables application adaptation to the constantly changing network topology, (v) Easy to discover and dynamically bound, (vi) Loosely coupled, reduces artificial dependencies, (vii) Stress interoperability, (viii) allows efficient service migration, which helps it perform well in the constantly changing dynamic MANET environment.…”

“…Web services also have some performance issues over mobile devices [8] and in case of Dynamic Service Discovery and Composition in Mobile Environments [9]. Further, deployment of traditional centralized architecture and bandwidth intensive protocol like SOAP is not suitable in MANET [13]. This paper presents a broad perspective of highly diversified research efforts on deployment of SOA for effective management of the services in MANET.…”

A dynamic and policy-controlled approach to federating information systems

“…The discovery process relies either on the capabilities of the Group Manager [4] or on the Cross-layer communication substrate (XLayer) [5] for discovery and grouping support.…”
